Electrical 94 Gt With Airbag Code 61

Mustang 1995 Air Bag Diagnostic Codes


Normal Operation
The air bag diagnostic monitor measures the resistance between the ground connection at its bracket and the reference ground at Pin 18. If the air bag diagnostic monitor measures a difference of more than 3.0 ohms between the ground at Pin 18 and the ground at its bracket, the air bag diagnostic monitor will store in memory and flash out a DTC 21 on the air bag indicator. Should the difference in resistance between Pins 18 and air bag diagnostic monitor bracket ground be serviced or otherwise reduced to less than 3.0 ohms, the air bag diagnostic monitor will flash out a DTC 61 (or a higher priority DTC if one exists) on the next ignition switch cycle.

Possible Causes
A high resistance reading at the air bag diagnostic monitor bracket ground can be caused by:

• A poor attachment of the air bag diagnostic monitor due to loose mounting, dirt, or corrosion at the air bag diagnostic monitor bracket mounting surface(s).
• A poor reference ground at Pins 10 and 18 of the air bag diagnostic monitor Circuit 57 (BK).

It sounds like the airbag diagnostic monitor may have been removed / replaced at some point (or it thinks it has). If you believe everything is in good shape again, you can try the code-clearing procedure in the attached link. The information at that link seems to indicate the code 61 shouldn't be permanent (just present at the next ignition switch cycle). But 61 seems to indicate the 21 is no longer present.

If you found that link then I'm not sure what you were asking. My post explains what causes a code 61, as does the link. It's customary to say 'thanks' around here as you'd left out those minor details and we don't happen to be mind-readers in our un-compensated quest to help you.

Letting the battery get weak (low voltage) can cause it to throw a code (disconnecting entirely does not). If the voltage goes low enough, the unit may even pop the fuse. You can find all of that information in the posted link, and you might end up having to replace a fuse and re-run the reset procedure a 7th time. If you're lucky (I've only had that happen a few times when it got so bad that all I got was a solenoid click on the starter) then it'll be just fine.
